Position coach: Greg Frey is in his third year. Last year, he helped coached a young unit to one of its best seasons. The IU line excelled in pass-blocking and helped the Hoosiers finish second in the Big Ten in total offense (442.0 yards per game) and fourth in scoring (30.8 points per game)

Strengths: The line will be led by left tackle Jason Spriggs and right guard Dan Feeney who both earned 2012 honorable mention All-Big Ten recognition. They helped anchor a unit that allowed one sack every 31.8 pass attempts - the fewest in the league.

Weaknesses: IU will have to replace senior center Will Matte. Collin Rahrig and Jake Reed are battling for that spot. Also as great as the Hoosiers were at pass-blocking, run blocking was at times an issue.

Watch for: Dimitric Camiel who redshirted last season. The coaching staff has high hopes for the 6-7, 308-pounder out of Houston. Also, Jake Reed played tight end as a freshman in 2011 but sat out last year as he moved to the offensive line.

The bottom line: With four returning starters this should be one of the best lines in the Big 10.
